We engaged in main production activty, & principal employer appointed only production Manager no other worker is engaged thro\' principal employer.Now pricipal employer want to shut the plant for renovation. We all are the permanent workers of contractor. Principal employer saying we r not their worker so they are nothing to do with us.Now our contractor wants to take settlement otherwise transfer to other states.
